# Vault Ownership Changes

## Transfer via Fusion Web App

1. Grant the Owner role to another address.
2. Test with the new address whether the action was successful.
3. If so, renounce your own role.

## Transfer via Smart Contract

For the core `PlasmaVault`, control is managed through role-based access control via `IporFusionAccessManager` rather than traditional ownership. You can transfer control by:

1. **Granting roles**: Use `grantRole()` to assign roles like `OWNER_ROLE`, `ADMIN_ROLE`, or `ATOMIST_ROLE` to new addresses&#x20;
2. **Revoking old roles**: Remove roles from previous controllers using the access manager

The role hierarchy must be respected (e.g., `ADMIN_ROLE` can grant `OWNER_ROLE`)
